Over the last year it is not hard to realise that the TARDIS Set has been victim to a lot of damage and wear. I truly believe the best thing for it would be to remove it from the Experience and find someway of restoring it or securing it from future damage such as walking on it (and those who break the rules and touch the console) to then either keeping it in storage or being put back into the Experience at a later date when it is much more secure.

It needs to be removed or atleast restrict close access to the set from the Public before it entirely falls apart and a piece of Doctor Who history/sets (only 10 years old) is ruined forever.

My personal opinion would be to replace it with what remains of Matt Smith's first TARDIS set (which was taken to the 50th Convention last year) which would survive longer than the Eccleston and Tennant TARDIS set.
